Cistoadenoma seroso unilocular macroquístico de páncreas

The differential diagnosis between macrocystic serous cystoadenoma and mucinous cystoadenoma is very difficult but is highly important due to the latter's potential for malignant transformation. We present a case of unilocular macrocystic serous cystoadenoma.Due to the impossibility of obtaining an accurate preoperative diagnosis, all macrocystic unilocular lesions, in an appropriate clinical context,must be resected.
